Our Stand UP/ Sit Down desk uses a Zen Office™ (Peace Bench™and Tilt Seat™) placed on top of an Eco Tower™. This configuration places the laptop screen at ideal eye level and the external keyboard and mouse at idea typing angle.
For sitting, simply reconfigure the pieces. Place the Tilt Seat™ on the floor and reverse the angle of tilt as shown. Then you will be sitting on the Tilt Seat™ and using the Peace Bench™ as a podium to raise the height of the laptop screen. Then put the keyboard and mouse on the surface of the EcoTower™.
